I checked the student information I saw that you only took the first lecture, and that you only took the input and output lecture for non-Python users, and I captured it. It seems like a malicious review was left by intentionally creating a sub-account, so I will contact Infraon separately and take action after confirming the facts. In addition, if you look at the top of my lecture description, there is already a comment that says, "Please definitely take the free lecture before taking the course." I am trying to make it so that as many people as possible can gain knowledge equivalent to the money they invested, such as through free lectures, real-time Q&A, and lecture modifications. One day after purchasing the course... Among them, you only took the 18-minute pre-explanation lecture and wrote this review... My heart hurts.
